Photocatalysis with Reversibly Coordinating Cerium Complexes (A03)

• Subject Area: Organic Molecular Chemistry - Synthesis and Characterisation
• Term: since 2021
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 444632635

We aim in this project to develop better-defined cerium photocatalysts bearing multidentate ligands and apply the ligand to metal charge transfer (LMCT) principle to new transformations, such as selective intra- and intermolecular C–H functionalizations in compounds bearing hydroxyl groups, oximes or hydroxamic acids. Moreover, to achieve selectivity in intermolecular C–H abstraction on oligohydroxy compounds selective hydrogen bonding to hydroxyl groups is proposed, which results in weakening and preferred abstraction of the -C–H bond by photocatalytically generated alkoxy radicals.
